- 'ro- ALL WHOM IT MAY concerns:

Be it known that I, GEORGE D. Goonnrcmbf Chicago, Cook county, Illinois, have ini'ented certain new anduseful Improvements in Peat-Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, rct'erenceheing had to the annexed drawings, consisting oftwo-sheets, inakinga part of thisspecification, in which- Figure 1 of Sheet No.1, is s transverse section on red line m y.

Figure 2, Sheet No. I, is a front view. I p

Figure '3, on Sheet No. 2, is vertical section-of the tempering-mill, with a portion of the lower case cut awa Figure 4, Ion Sheet No. 2, is a top riewof the horizontal part of the mill, with a. portion of the case and .the tempering-mill removed Figure 5, Sheet No. 2, 1s across-section of the shafts at red lines 2. V Figure 6, Sheet- No. 2, is an enlarged view of the plate or socket 71, showing the method of fastening it to the plate, and showing how the pin e'is attached to the socket.

' The nature and object of" my invention consist in constructing a machine in which tne peat will be compressed by means of screws; in providing such ruachine with an adjustable automoticdevicetdr cutting the, compressed peat into blocks of suitable size for use, as it -oomes from the machine; in combining-two or more tempering-mills in the some cylinder; in providing edjnstahle bearings for the inner shaft of thtempei-ingmill, and in the several combinations hereinulfter mentioned. i

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation i i represents the hex or cylinder, into whrcn the peat is to he introduced and being the case of the tempering mill, and whey be made as shown, or of any other suitable form and size. B is e, hollow shaft, to which are attached the knives or cutters a, which cntand mix the .peat. C is a. shaft within the shaft 13, on which the screw-hector E is i'astened. These shafts are supported and held in place as shown, or in any other suitable manner. and two or more sets of shafts, knives, and boaters niuy'be combined and used in the some znill. Beneath each screw-heater Ejareplaced two expelling-screws H, runningin horizontal troughs I, by means of which the peat. is compressed and expelled. The case A is to .be securely fastened to the horizontal part of the mill containing the screws H. J are openings through which the pest is expelled, there being one for each expellingscrew. The flanch of the expelling-screws is somewhat smaller at toe-end towards the openings J. than at the other end, end the troughs'are correspondingly contracted taperingly', which facilitates the pressing of the peat. The ends ot'i-these screws H towards the openings J have no bearings, 'but cresupported in the troughs,

the contracted portion of the troughs being only lai' ge enough to permit the corresponding portion of the screws to move freely therein. The other ends of these expelling-screws are secured in substsnti a bearings t, or" proilidod with suitable means of connecting the same with the power. F is a knife or cutter, used for cutting the peat into pieces of proper length. 7 The knife is pivoted at g tothe stendurdp. The knife has spaces between the cutting-parts,nnd there is n cutting-portion for each opening J. The for. of theknife, and its position when elevated, are shown b y the red lines infig. 2, the letter k indicating the cutting-pi rtsei' the knife, the dgesof which are inclined as -show-u, to facilitate the cutting. The cutting-parts of the knife workin slots,

and the ends in. grooves in'thestandard c. Two knives may be used instead of one,'each.being half the length of that shown, andesch being operated by an automutic device, hereinafter dosciibedmlsced at e'schend of the mill. The pressure required for post varies with the quality andkind, hence on 'autcmstic device for cutting peat into pieces of desired length as it comes from the mill should be adjustable, in order to be adapted to mi-ions kinds of peat, a p

My device for this purpose is as follows: K is a circular metal plate, provided with two series of conceu tric slots d. In each of thcs'e slots I fasten, by means of the nut 1', a believer bent plate or socket, It. In the face of the socket h is a recessed groove in which is a nut, j, which holds the pin a in place. The plste'K is permanently attached to one end oi the shaft 11, supported onthe'standdrd n at one end, and at the other and properly supported and connected with the. power by means of awhecland belt, as shown at m, or insome other suitab manner. A bar or arm, f, is ,attaohed lay means of a bolt to one end of l the knife-leverG, as shown in fig. 3, the other end of the lever being pivotedtcthe knife at its centre. Eacl 'end of this arm j is so inclined is to form acom, the inelinajtion being in the some direction at each end. The ends of the arm are made much thicker than the other part, and so shaped that when the pins in the outer series of slotspass over the upper and of the arm, thepinr in the other series can passtho arm without touching it. The lower ehd of the arm-is somewhat shorter than the upper. The outer pins 0 passing over the cam at the upper end of the bar-f, raise the knife;- the inner pins passing over the cam at the lower end of the arm force the knife down, and the peat" is out. In the arm f are slots to receive the guides o. The knife or closing-plates may be so constructed as to revolve, or have any other suitable meclmhical uiovemcnt. The barf is kept in an upright position by means .of the standard I, provided with the guides a. The socket h is adjustable in the slots: by means of the nut Lend the pins 2 are also adjustable in the socket 7:, by means of the nutj. By using a greater or less number of pins e,'or. by adjusting a. part of them so that they will not strike the cams, the time during' which the paint will be pressed can be varied, and'the length of the pieces of cutpent can be also varied in the some manner. Inmachines of ordinnry'siz'e, the distance between the end of the oxpell'ingscrews and the cutter or knife will be about six inches. In this'apace'tlio peat will be compressed, and this space will be made of the scmediauieter throughout. The innbhphaft 0 is liable to become loose by wean, To remed'y'thisI provide the outer shaft B with recesses in the inside and near the bridge, and in these recesses I fit jonrnal-b'earingsr, as shownin fig. 5. These bearings are-adjustable by rneans of the screws a, and'cnn baadvanced as the shaft C or the bearings r wear away. The face of these hearings may he fuccdwith Babbit or some other soft metal. i

In operation the peat' is put into tho mill, when, after being pulverized by the knives a, it is. forced donnupon the expclling-scrows'li by the screw-beater The expelling-serene cnrry'thc peat through the t roughe- I, and the poet is compressed between the end of the screws andthelgnifol By means of the automatic-device described, the knife is raised and forced down otproperintervels, cutting tho-pemintocblooks for us Having thus'fully described my invontiomwhct I claim as new, and desire-to seo'ure' by Lettcrs'Pa'tcnt, is--'-- 1. The adjustable bearing for the shoit B, composc'd of two or more segtnents r, constructed and operating substantially its-described. g i I 2. The sepaTrute troughs I, located below the temporing-milh'nhen more than one expelling-screw is employed, so ns-to giveeoch screw a. separate ondindepondont action, substantially as specified.

3. The cutter or knife F, for cutting the material into suitnblolongths in apoat-machine'hnving a continuous dischargefrom the expelling-mill, substantially as specified. r

4. Closing tho. mouthof the die by an adjustable intermittent stop or knife, when so arranged that the movements can be varied with respect to the movements of the other operating parts of the machine, substantially as specified. v

5. The double slotted plate or wheel K, provided with the sockotc Iv and pins {for the purpose of.cdjusting the movements of the cutter-stop or l-z'nife F, substantially he described. I v

6. The combination of the seporototroiighs I, expelling-screws H, and cutter-stop F, with a tempering mill, substantially as specified.
